Javafx Event handler on GridPane Cells

Question

I have the gridpane set up just fine. But how to put event handler in each cell? Like mouse double click and right click. Could someone give me an example, please? Thank you!

Answer 1

You don't specify what you want exactly,but i hope this examples can help you

First example (I add the same event for all nodes)

 */
package stackover;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.GridPane;

/**

public class FXMLDocumentController implements Initializable {

    @FXML
    private Label label;
    @FXML
    private GridPane gridPane;

    @FXML
    private void handleButtonAction(ActionEvent event) {
        System.out.println("You clicked me!");
        label.setText("Hello World!");
    }

    @Override
    public void initialize(URL url, ResourceBundle rb) {

        addGridEvent();

    }

    private void addGridEvent() {
        gridPane.getChildren().forEach(item -> {
            item.setOnMouseClicked(new EventHandler<MouseEvent>() {
                @Override
                public void handle(MouseEvent event) {
                    if (event.getClickCount() == 2) {
                        System.out.println("doubleClick");
                    }
                    if (event.isPrimaryButtonDown()) {
                        System.out.println("PrimaryKey event");
                    }

                }
            });

        });
    }

**}

Second example**

private void addGridEvent() {

        Button button = new Button("hi");
        //You can use OnAction 
        button.addEventHandler(EventType.ROOT, (event) -> {
            if (event.getEventType() == ActionEvent.ACTION) {
                System.out.println("ActionEvent");
            }
        });
        gridPane.getChildren().add(button);
